Can you please use reply-all and not top-post?

I did some research.
The force flush has its roots in uml-patch-2.4.9-4, in form of
flush_tlb_kernel_vm().
We have kind of a changelog:
http://user-mode-linux.sourceforge.net/old/changelog-uml-patch-2.4.9-4.bz2.html
"Fixed the process segfaults that happened when the system was swapping"

In uml-patch-2.4.9-8 it gained further changes.
"Fixed and cleaned up the tlb flush code".

I think it is high noon to review/rethink that code...
